4309 and 4367 are members of JBL's Studio Monitor series of speakers. Below you can find the loudspeakers from this series.
What size room are the JBL 4309 and JBL 4367 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the JBL 4309 and JBL 4367 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

4309 features a 1" Teonex Compression Driver Tweeter and 1 x 6.5" Pure Pulp Woofer with a Crossover frequency at 1.6 kHz. On the other hand, the 4367 features a 3" Teonex Compression Driver Tweeter and 1 x 15" Pure Pulp Woofer with a Crossover frequency at 700 Hz.
Frequency Response
4309 has a frequency range of 42-30k Hz whereas 4367 has a frequency range of 30-40k Hz. With a minimum frequency of 30Hz, the 4367 can go significantly deeper on the low side and provide stronger bass compared to the 4309's min frequency of 42Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

High Frequency
Bookshelf Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
4309 is a 4 ohms speaker compared to the 4367 which has a nominal impedance of 6 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the 4309 can provide this impedance level.
These two speakers also have different sensitivity levels. 4309 sensitivity is rated at 87 dB and the 4367's is rated at 94 dB. This 7 dB difference makes the JBL 4367 a more sensitive speaker compared to JBL 4309, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
4309 can handle a max power of 300 watts RMS from the amp the whereas 4309 has a max power handling value of 150 watts RMS , 150 watts less than the 4367.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
4309 features Binding post type posts and 4367 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare JBL 4309's and JBL 4367's external dimensions. JBL 4309 has external dimensions of 419.0 x 260.0 x 227.0mm ( 16-1/2 x 10-1/4 x 8-15/16inch) whereas JBL 4367 has external dimensions of 941.0 x 560.0 x 425.0mm ( 37-1/16 x 22-1/16 x 16-3/4inch) .
JBL 4367 is clearly the larger of the two speakers. Its body is 300mm wider, 522mm taller and 198mm deeper than JBL 4309.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the JBL 4309 is approximately 590.2cm2 / 91.5inch2 and base area of the JBL 4367 is approximately 2380.0cm2 / 368.9inch2. The 4309 requires 75% less surface area than the 4367 which gives it a small advantage on placement in tight spaces.
